% Nov. 12, 1929. c, HORNBY ELECTRIC WATER HEATER Filed May 29. 1928 Inventor (167% 15 0371; 8) guwwgi g Patented Nov. 12, 1929 CHARLES H. I-IORNBY, or sonnnncrmnxnnw YORK ELECTRIC WATER HEATER Application filed May 29, 1928.

The present invention relates to improvements in electric water heaters and has reference more'particularly to an apparatus for keeping water or saline solution at a constant temperature of about 110 F, which solution or water is contained in a douche can, such as is used in hospitals.

The water or saline solution is allowed to drip, drop-by-drop, in being administered to the patient- It has been experienced that in carrying out this treatment, the solution, in the douche cansoon become cold. It is therefore one of the principal objects of the present invention to provide a means for keeping the water or saline solution at a constant temperature of about 110 F. This will permit the iiuid to be administered to the patient in a warm condition.

A further object of the invention is to provide a water heater that is adapted for immersion into the receptacle containing the water or saline solution, means being provided for supporting the heater in the receptacle.

A further object is to provide a heating device of the above mentioned character which is simple in construction, inexpensive,

strong and durable, and further well adapted to the purpose for which it is designed.

Other objects of the invention will become apparent as the nature of the invention proceeds and when taken in connection with the accompanying drawing.

In the accompanying drawing, forming a part of this application and in which like numerals designate like parts throughout the several views:

Figure 1 is a detail perspective view of the electrically operated heating device, embodying my invention, and

Figure 2 is a vertical sectional View therethrough.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a cylindrical casing, which is open at its upper end, the same being formed of any suitable metal, preferably copper.

A removable lid 2 is provided for the open Serial No. 281,458.

upper end of the receptacle, and secured centrally in the lid is the electric lamp socket 3, which is of the conventional construction, the electric lamp 4 being secured in the socket for disposition within the copper receptacle or casing 1, in the manner as clearly shown in Figure 2.

The conductor cord that has connection with the socket 3 is shown at 5, and a plug 6 of the conventional construction is carried by the free end of this cord for attachment to any suitable wall socket or light fixture. A switch 7 is associated with the lamp socket 3 in the manner also well known in the art. A series of arms 8 extend radially from the upper portion of the casing in an outward direction, the inner ends of these arms being soldered or otherwise secured to the casing and the outer ends of the arms terminate in downwardly disposed hooks 9, that engage over the upper edge of the douche can (not shown) and in which is contained the water or saline solution that is to be heated.

The provision of the arms 8 provide a means for properly supporting the heating device in an immersed manner in the liquid, in the douche can, and for the purpose of maintaining the casing of the heating device in an upright position, a lead weight 10 is placed in the bottom of the casing.

The lid 2 is provided with a relatively small window 11, whereby it can be readily ascertained whether or not the electric lamp 4 is burning.

By changing the bulb to either a larger or a smaller wattage, the temperature can be either raised or lowered. The use of my improved electric heating device is thought to be readily obvious from the construction disclosed and when employed in conjunction with a douche can, the water or saline solution will be kept at a constant temperature or approximately 110 F.

The simplicity of my improved heating device enables the same to be constructed at a very low cost and furthermore the parts can be readily and easily assembled or disassembled whenever necessary.

WVhile I have shown the preferred embodiment of my invention, it is to be undercasing, and a series of supporting arms eX- tending radially and horizontally from the upper portion of the casing for rest upon the upper edge of a receptacle containing the liquid to be heated, whereby the casing is centrally suspended in a receptacle, the outer ends of the arms being bent to form downwardly extending hooks to prevent displacement of the suspended heater from the receptacle.

In testimony whereof I affix my signature.

CHARLES H. HORNBY.
